' Specification forming part of Letters Patent No. 130,058, dated July30, 1872.

To all whom it may concern:

Be it known that I, PERLEY LAFLIN, of

. W'arren, in the county of Worcester and Com;

nionwealth of Massachusetts, have invented certain new and usefulImprovements in Guides for Spooling and Winding Machines; and I dohereby declare that the following is a full,

clear, and exact description of the same, reference being hadto theacompanying drawing,

which forms a part of this specification, in

Whicha Figure 1 represents a side view of my safety and cleaningguide.Fig.2 represents a front view. Fig. 3 represents a rear view. Fig. 4represents a plan view. Fig.5 represents a vertical section at line A BFig. 3; and Fig. 6 represents a vertical section at line GD,Fig.1.""

.. To enable others skilled in the art to which my invention belongs tomake and use the same, I will proceed to describe it in detail. Thisinvention relates to certain improvementsin devices for guiding yarnupon spooling and winding machines, as hereinafter fully described. 7

In the drawing, the parts markedA and B represent the guiding-jaws,which are supported by upright arms A B", the lower ends of which arepivotedin slots at the extremities of a short cross-bar, D, by thepivot-pins d d, as indicated. The jaws A B are provided with curvedflanges a b, so that when the two are placed together in workingposition they form a cylindrical head or box, open at one side, as theflanges do not form a full circle, and having aspace between the twopartsof sufficient width to permit the free passage of the yarn throughthe guiding-jaws. The jaws A B are held to each other by a bar, E, whichalso serves as ayarn-support, its central por- 7 tion being formedcylindrical and smooth, and

a screw-thread out upon one of its extremities, while the other isprovided with a smooth hemispherical head. The bar or yarn support Epasses through one of the jaws and screws into the other in the mannerillustrated, and by turning it the distance or space between the jaws AB can be increased or diminished to adjust the guide to various-sizedyarn. In the upper front part of the jaws A B are arrangedupwardly-projecting plates 0 c, the inheredges of which incline down tothe opening between the jaws, and to the rear side of the jaws A B arefixed plates ff, the inner edges of which are also inclined toward theopening, as fully shown in Fig. 3. These plates 0 and f facilitate theplacing of the yarn between the guide-jaws, and cause it to be drawninto the jaws when'the spooling or winding machine is started, eventhough the yarn is only thrown carelessly across the guide.

The lower ends of the plates f are inclined inward, so that the yarnwill not catch thereon when it has from any causebeen pressed down belowthe ends of said plates. Within the cylindrical head formed by the jawsA B there are small lugs or catch-pieces e 6, one of which, 0, is madein the form of a latch-hook and is secured to the jaw B, and the other,e, is made in the form of an inclined lug and attached to the under sideof the curved flange at the upper part of the jaw A. These catch-piecese 0 project past each other and prevent the yarn from being raised outfrom the jaws of the giiide without breaking the yarn, so that theoperator cannot raise the yarn from the guide, and thereby permit anyaccumulation of dirt and loose substance that may have been strippedfrom the yarn during its passage through the guide to pass the guide andwind onto the spool, as is the frequent practice with the ordinaryguides in use. The yarn passes through the jaws of the guide, asindicated by the broken line I Figs. 1 and- 5. The lower ends of the uprights A B, where they 'are'pivoted to the cross-bar I), are made withinwardflanges or ribs g, as shown, so that the parts will be stifi andlight, and so that the shoulders h may rock upon and be supported bythe'cross-bar, thus relieving the pivot-pin from excessive weary Ascrew-bolt, G, projects downward from the central part of the cross-barD, which is screwed into the guide-bar of the machine, as indicated inFig. 1, and thus supports the guide in proper position.

Among the advantages obtained by constructing the guides in the mannerherein shown and described may be mentioned the following: It cleans theyarn'in a very perfect manner by .removing adhering particles of dirt,which are taken off from the yarn by the edges of the flanges a b andplates f. These particles which pass the flanges a b are thrown to thesurface of the yarn by its being drawn over the supporting-bar E, andare then taken off by the edges of the plates f. My improved guide ismuch less liable than is the ordinary guide to become choked or cloggedby the accumulation of lint and dirt in front of the jaws, as it isscraped ofl' from the yarn by the flanges a b and plates f. This isowing to the fact that the jaws, being pivoted at d d, are in constantvibration by the jar of the machine, so that the lint and dirt areshaken oil from the jaws. The form of the jaws is also such as tofacilitate the release of the lint and dirt. Another important advantageis that the guide holds the thread or yarn so that the operativescannot, as with the old guides, raise the yarn from the jaws when thelatter become choked and permit the accumulation of lint or otherimperfections to wind onto the spool with the yarn; but by raising theyarn it becomes broken, and the operative is then required to tie theends, and as a matter of convenience, .if for no other reason, they willat the same time remove the imperfect or clogged portion of the yarn.The spools are thus wound with cleaner and more perfect yarn, and all ofthe subsequent operations through which the yarn passes are therebyfacilitated, while less imperfections are woven into the cloth. Again,by making the adjusting-screw or supporting-bar E with a round smoothhead the operatives are prevented from opening the jaws or disarrangingthe adjustment thereof after they have been properly arranged by theforeman.

In lieu of making the catch-pieces e e in the form herein shown, saidcatches may be made in the form of spring-hooks, so that they will yieldto allow the yarn to pass them; or they may be made in the form ofdownward-curved hooks cast upon or otherwise attached to the flanges ofthe jaws; and, if desired, a single catch may be used similar to the lug6, but with its end extended and curved downward sufficiently to insureits secure hold upon the thread. A rubber spring may be arranged uponthe screw-bolt Gr between the lower ends t z of the uprights A B forpressing said ends outward, thereby causing the jaws A B to bear uponthe yarn with a yielding pressure within the limit of their adjustment.

' Having described my improved safety and cleaning guide for winding andspooling yarn,

what I claim therein as new and of my invention, and desire to secure byLetters Patent, 1s-- 1. A spoolingguide constructed substantially asdescribed, whereby the thread or yarn will enter the guide freely, butcannot be withdrawn or lifted out of the guide without breaking thethread. 2. The combination, with the pivoted or vibratory jaws A B, ofan adjusting and threadsupporting screw-bar, substantially as shown andset forth.

3. The combination, with the jaws AB, of a central thread-support andcatch device, substantially as and for the purposes set forth.

4;. The combination, with the upper part of the guide-jaws A B, ofinwardly-inclined upward-projecting plates 0 eff, substantially as andfor the purposes set forth.

5. The combination, with the rear part of the guide -ja-ws A B, of thedouble-beveled plates f f, substantially as and for the purposes setforth.

6. The combination, in a guide for supportin g and winding yarn, of thevibrating jaws A A B B, provided with guiding and cleaning flanges a band plates 0 c f f of the catch-pieces e 12, supporting and adjustingbar E, cross-bar D, pivots d d, and screw-bolt G, all constructed andcombined for operation substantially as and for the purposes set forth.
